2. Description of the Related Art Horizontal rotating shelves are well known as high-speed cargo handling equipment that carries and transports a plurality of buckets storing a plurality of articles. Normally, horizontal rotating shelves are driven by drive devices and power transmission mechanisms.
A plurality of shelves are made to run along a guide rail. -Then, the loaded buckets and the like are loaded into or taken out of the warehouse by the loading/unloading equipment installed on the left and right sides or one side of the rotating section of the horizontal rotating shelf. However, when at least two or more buckets are mounted on one shelf, the attitude angle (position) when entering and exiting the warehouse using the loading/unloading equipment consisting of one transfer machine located in the revolving section may not match. First, there was a problem in that the transfer machine had to be rotated to load and unload the two buckets on the left and right.

Examples of these techniques are disclosed in Japanese Patent Publication No. 37163/1983.

[Problem to be solved by the invention]

When double forks were used, the cargo was transferred in a straight line to the target fixed shelf.

However, if one or more sets of loading and unloading equipment for transferring goods to and from the rotating shelves are installed in the revolving section, it is possible to load and unload two buckets mounted on the shelves at the same time, or to load and unload only one bucket. This poses a problem in that transport efficiency cannot be improved because a positioning operation is added that takes into account the stop position, that is, the delivery posture of the bucket corresponding to one transfer machine.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method and apparatus for transferring a horizontal rotating shelf that can further increase the throughput of a horizontal rotating shelf in which two buckets are mounted on one shelf.

[Means to solve the problem]

The above purpose focuses on setting the sprocket stop position at a position where the attitude of the transfer device of the loading/unloading equipment installed in the revolving part of the horizontal rotating shelf matches the attitude of the two buckets inside the shelf. By installing two transfer devices for loading and unloading equipment opposite to the two buckets mounted on one shelf, it is possible to load and unload two items at the same time or to load and unload only one item. be done.

[For production]

The present invention involves arranging two transfer machines of loading and unloading equipment in parallel in the revolving section of a horizontal rotating shelf, facing the positions of two buckets mounted in one shelf, and responding to operation commands from a control device. The horizontal carousel and loading/unloading equipment operate in synchronization.

As a result, the efficiency of loading and unloading loading and unloading work performed between the horizontal carousel and loading/unloading equipment is increased, resulting in a significant improvement in throughput.

〔Example〕

Hereinafter, the present invention will be described in detail based on specific embodiments shown in the drawings.

First, the overall structure of the horizontal rotating shelf will be explained with reference to FIG.

Reference numeral 10 denotes a horizontal rotating shelf having a rectangular shape in the left and right direction, connected to a large number of columns 11 by a plurality of horizontal connection rods,
It is formed. A guide rail m is made up of an outer rail 4 and an inner rail n, supporting wheels Z3.24 attached to the shelf (9), and is bent into a long elliptical shape in the left and right direction along the outer periphery of the horizontal rotating shelf 10. horizontal shape,
They are laid at a required distance from each other in the vertical direction.
